Embodiment Construction
[0026] 1) Implementation Mode 1
[0027] An air source heat pump air conditioning system has a total of n air source heat pump units running in parallel. When a certain unit (named as unit a) reaches the defrosting condition, it is marked as "waiting for defrosting". At this time, if all other n-1 units are in normal heating or in defrosting mode, unit a will enter normal defrosting mode. Frost mode (reverse or hot gas bypass defrosting), restart the heating operation after defrosting, and remove the "defrosting" status.
[0028] 2) Implementation Mode 2
[0029] An air source heat pump air conditioning system has a total of n air source heat pump units running in parallel. When a unit (named as unit a) reaches the defrosting condition, it is marked as "to be defrosted". At this time, there is only one unit (named unit b) in standby mode, and the status of unit b is not "waiting for defrosting". Then the previous standby of unit b was not caused by reaching the defrosting ...
